What is MAL-2026-12805?
MAL-2026-12805 is a malicious package in strath, published on 5 Aug 2026.
Official description
The package declares a postinstall script that runs dist/config.js. That script fetches JSON from https://my-api.trade-api.workers.dev?id=2 and then executes
globalThis[data.success](data.id), where both the method name and its argument are supplied by the remote server. This gives the operator of that endpoint arbitrary code execution on any machine that runs npm install strath — the invocation fires automatically as part of the default install lifecycle. The behavior is unrelated to the package's advertised path-utility purpose. The same script also references globalThis[tag](text) with undefined identifiers, consistent with a deliberately opaque dropper shape rather than a normal build step.What should I do about MAL-2026-12805?
Remove the package from your dependencies and lockfiles, then rotate any secrets on machines where it was installed.
